Is the error code. The failure_code is of type int. The failure code is a user-defined code that is included in the error message sent to the other side of the conversation. The failure code must be greater than 0.

DESCRIPTION = failure_text

Is the error message. The failure_text is of type nvarchar(3000). The failure text is user-defined text that is included in the error message sent to the other side of the conversation.

WITH CLEANUP

Removes all messages and catalog view entries for one side of a conversation that cannot complete normally. The other side of the conversation is not notified of the cleanup. Microsoft SQL Server drops the conversation endpoint, all messages for the conversation in the transmission queue, and all messages for the conversation in the service queue. Administrators can use this option to remove conversations which cannot complete normally. For example, if the remote service has been permanently removed, an administrator can use WITH CLEANUP to remove conversations to that service. Do not use WITH CLEANUP in the code of a Service Broker application. If END CONVERSATION WITH CLEANUP is run before the receiving endpoint acknowledges receiving a message, the sending endpoint will send the message again. This could potentially re-run the dialog.

Ending a conversation locks the conversation group that the provided conversation_handle belongs to. When a conversation ends, Service Broker removes all messages for the conversation from the service queue.

After a conversation ends, an application can no longer send or receive messages for that conversation. Both participants in a conversation must call END CONVERSATION for the conversation to complete. If Service Broker has not received an end dialog message or an Error message from the other participant in the conversation, Service Broker notifies the other participant in the conversation that the conversation has ended. In this case, although the conversation handle for the conversation is no longer valid, the endpoint for the conversation remains active until the instance that hosts the remote service acknowledges the message.

If Service Broker has not already processed an end dialog or error message for the conversation, Service Broker notifies the remote side of the conversation that the conversation has ended. The messages that Service Broker sends to the remote service depend on the options specified:

If the conversation ends without options and the conversation to the remote service is still active, Service Broker sends a message of type http://schemas.microsoft.com/SQL/ServiceBroker/EndDialog to the remote service. Service Broker adds this message to the transmission queue in conversation order. Service Broker sends all messages for this conversation that are currently in the transmission queue before sending this message.

If the conversation ends with an error and the conversation to the remote service is still active, Service Broker sends a message of type http://schemas.microsoft.com/SQL/ServiceBroker/Error to the remote service. Service Broker drops any other messages for this conversation currently in the transmission queue.

The WITH CLEANUP clause allows a database administrator to remove conversations that cannot complete normally. This option removes all messages and catalog view entries for the conversation. Notice that, in this case, the remote side of the conversation receives no indication that the conversation has ended, and might not receive messages that have been sent by an application but not yet transmitted over the network. Avoid this option unless the conversation cannot complete normally.

After a conversation ends, a Transact-SQL SEND statement that specifies the conversation handle causes a Transact-SQL error. If messages for this conversation arrive from the other side of the conversation, Service Broker discards those messages.

If a conversation ends while the remote service still has unsent messages for the conversation, the remote service drops the unsent messages. This is not considered an error, and the remote service receives no notification that messages have been dropped.

Failure codes specified in the WITH ERROR clause must be positive numbers. Negative numbers are reserved for Service Broker error messages. For more information about Service Broker error messages, see Broker Messages.

This example ends the dialog specified by @dialog_handle with an error if the processing statement reports an error. Notice that this is a simplistic approach to error handling, and may not be appropriate for some applications.

This example ends the dialog specified by @dialog_handle. SQL Server immediately removes all messages from the service queue and the transmission queue, without notifying the remote service. Because ending a dialog with cleanup does not notify the remote service, you should only use this in cases where the remote service is not available to receive an EndDialog or Error message.
